Unlike most services, they don't appear to offer a free trial, which would rule out signing up, watching this series, and then cancelling.

TAN does (or at least did) advertise a 'free trial', which in theory works by them not charging for the subscription for the first 2 weeks, allowing the user to cancel before they're charged. TAN's payment system is buggy from time to time, so it might take some extra effort to make sure the user is not charged (I was charged for my free trial even though I tried to cancel, but then I decided to let it continue rather than make a request to fix it).
